双顶和双底 - 您如何应对它们？ (Double Tops & Double Bottoms - How do yo)

Double tops and bottoms, they seem to me one of the simplest and most rewarding patterns you can spot on the charts. No trendlines, no fibs, no moving averages. Just those two (or sometimes three) dots you gotta catch and ... there you go.

Seems a simple strategy in hindsight, but then what best tactics do you use?

What do you do when there seems to come a nice fish, it bites the hook and comes all the way up to you? : Looks nice? Yeah, but what if that fish turns out to be a very big one that jumps on your boat and draws you with it to the depths of the seas? (Hope you get the picture).

How would you for example trade (have traded) this chart with double top strategy:
